Title: Driving method for ink-jet head and driving device
Inventor: FUJII MASAHIRO
IPC: B41J2/055
Filed: 2000-08-21
Abstract: PROBLEM TO BE SOLVED: To provide a driving method for an electrostatic ink-jet head capable of preventing deformation of the partition wall by an ink ejecting operation even in the case a partition wall between pressure chambers is thinned by achieving a high density. SOLUTION: With a vibration plate 51(3) of an ejection nozzle 11(3) of an ink-jet head 1, a vibration plate 51(2) of an adjacent non-ejection nozzle 11(2) is suctioned on an individual electrode. In the state suctioned thereto, ink droplets are ejected from the ejection nozzle 11(3). Thereafter, the vibration plate 51(2) is detached from the individual electrode side moderately. Since the compliance of an ink pressure chamber 5(2) on the non-ejection nozzle side is kept in a small state, deformation of a partition wall 8(2) between the ejection nozzle and the non-ejection nozzle by the ink pressure fluctuation can be prevented. Thereby, deterioration of the ink ejection characteristics derived from the deformation of the partition wall can be prevented so that a printing operation by a highly sophisticated and dense printing quality can easily be realized.
